It is likely that Si and P would substitute for each other in a solid solution.

True False

the answer would be a

a electronegativity decreases beacuse the size of nucleus is bigger.

substituting a hydrogen atom with a halogen in a hydrocarbon:

- the single bond remains single. a is wrong.

- the bond with hydrogen is as strong as with a halogen. c is wrong

- a hydrocarbon is saturated if there is no double bond. we do not know that so d is wrong.

- carbon will always have four valence electrons. e is wrong.

by elimination, the correct answer is b. the boiling point of the new compound increases.

idk what is it? is this a question that you know the answer or u dont
